all whom t t mdy concemk have {invente 5" ment in Saddle-Blocks for Scales, ofwhich thelfollowing is affulhclear, and 'ergactde-i -scr 1pt1on, reference being: had fto" the ac- I showing my 1mproved saddleblockapplied for use on the scale beam; 2. is-ia secon the line II I I= of Fig.1. Y My, invention relates to weigh and it particularly relates to: track tional end elevation of the scale beam taken dg a apted for. use construction.

The object oi the invention is to provide 'an imp'roved'saddle block for-such scales 'bythe use of which disarrangement of the parts which cause the scales to weigh in correctl will beprevented and by the use of whic the parts are easily and quickly K'putl in-place in assembling orrepairlngthe sca es.

The invention'consists; in a saddle block having a bearing faceflwhich willalways be pcheapliy 1,I,i, '-,t he roper position relative to the loo whidli the saddle block 'is placed and which is of circular form and which contacts the knife edge coacting with-thesaddle beam having knife edges 3 and 4.- 'The knife edge 3coope'rateswith, the eye ofv the pin 5, whichis'fixed to thefo'undation of the 40 scale in an}? desiredm'anner'to'forrn a fulcrum for t, is. beam. Loops 6 are used to connect the beam? t'ofthe'j cross beams 7,. 7,

the ends of the loofirsv 6 being secured on the knife'edges8 whic are secured in the ends 15 of the beams 7.. The loops v6. extend'ulQ wardly around th'efjknife :edge'sf- {l'-'iI1jt e beam 2 and in each of-the' loo s. 6 is my improved;saddle ,block 9. he saddle permitting blocks are "cylindricalfand are; provided with :the c'ylindrical'.opleniitilgisf 10 m which e e e geseare the op ositeifendej offt inserte Thegeuteiiedgel of the" cylindrical sa b ckstee 5.5 o the' jsaddlef blo.c and; also provided loop.

Heretofore with'such loops, the saddle. block has been'constructed from itsiseat. in the loop and in this waychange the distance between the bearing face in the saddle blockand the of the bottomportion of the loop and disarto weigh incorrectly,

The advantages of my-invention are many and-will be'ap' arent to those skilled in the art. The sad le blockcan be easily and made and. by having a continuous curve bearing faceon its inner surface instead of the straight .face as used on such blocks heretofore, the accuracy of the weighing mechanism is largely'increased. Modifications in the construction and ar- "rangementof the parts maybe made without departing from my invention.
